The prenatal and early postnatal period is highly sensitive to environmental exposures that may interfere with the developmental programming of the immune system leading to an altered disease risk in later life. To clarify the role of early influences in activation or exacerbation of autoimmune diseases like rheumatoid arthritis (RA) we investigated the effect of maternal exposure during the prenatal and lactational period of DBA/1 mice to the plasticizer benzyl butyl phthalate (BBP) on the development of RA in the offspring. Using a mild collagen-induced arthritis (CIA) model, maternal BBP-exposure increased both the prevalence and the severity of RA in the progeny compared to un-exposed dams. Additionally, maternal BBP exposure led to elevated serum IgG1 and IgG2a level in the offspring and increased the IFN-γ and IL-17 release from collagen-re-stimulated spleen cells. Transcriptome analysis of splenocytes isolated from 3-week-old pups before RA-induction revealed considerable changes in gene expression in the offspring from BBP-exposed dams. Among them were regulator of G-protein signaling 1 (rgs1), interleukin-7 receptor (il-7r) and CXC chemokine 4 (cxcr4), all genes that have previously been described as associated with RA pathology. In summary, our results demonstrate that perinatal exposure to BBP increases the susceptibility of the offspring to RA, probably via a phthalate-induced disturbed regulation of RA-relevant genes or signaling pathways.

产前和哺乳期的邻苯二甲酸盐暴露会增加小鼠对类风湿关节炎的敏感性。

产前和产后早期对环境暴露高度敏感,这可能会干扰免疫系统的发育程序,从而导致以后生活中疾病风险的改变。为了阐明早期影响在类风湿性关节炎(RA)等自身免疫疾病的激活或加重中的作用,我们研究了母体在DBA / 1小鼠的产前和哺乳期暴露于增塑剂邻苯二甲酸苄基丁酯(BBP)的影响后代的RA 与未暴露的母犬相比,使用轻度的胶原蛋白诱发的关节炎(CIA)模型,孕妇的BBP暴露会增加后代RA的患病率和严重程度。另外,母体BBP暴露导致后代的血清IgG1和IgG2a水平升高,并增加了胶原蛋白刺激的脾细胞中IFN-γ和IL-17的释放。RA诱导前从3周龄幼犬中分离的脾细胞的转录组分析显示,暴露于BBP的水坝后代的基因表达发生了显着变化。其中包括G蛋白信号传导1(rgs1),白介素7受体(il-7r)和CXC趋化因子4(cxcr4)的调节剂,所有这些基因先前都被认为与RA病理学有关。总而言之,我们的研究结果表明,围产期接触BBP可能会增加后代对RA的易感性,这可能是通过邻苯二甲酸酯诱导的RA相关基因或信号通路的调控而引起的。RA诱导前从3周龄幼犬中分离的脾细胞的转录组分析显示,暴露于BBP的水坝后代的基因表达发生了显着变化。其中包括G蛋白信号传导1(rgs1),白介素7受体(il-7r)和CXC趋化因子4(cxcr4)的调节剂,所有这些基因先前都被认为与RA病理学有关。总而言之,我们的研究结果表明,围产期接触BBP可能会增加后代对RA的易感性,这可能是通过邻苯二甲酸酯诱导的RA相关基因或信号通路的调控而引起的。RA诱导前从3周龄幼犬中分离的脾细胞的转录组分析显示,暴露于BBP的大坝后代的基因表达发生了显着变化。其中包括G蛋白信号传导1(rgs1),白介素7受体(il-7r)和CXC趋化因子4(cxcr4)的调节剂,所有这些基因先前都被认为与RA病理学有关。总而言之,我们的研究结果表明,围产期接触BBP可能会增加后代对RA的易感性,这可能是通过邻苯二甲酸酯诱导的RA相关基因或信号通路的调控而引起的。所有先前被描述为与RA病理相关的基因。总而言之,我们的研究结果表明,围产期接触BBP可能会增加后代对RA的易感性,这可能是通过邻苯二甲酸酯诱导的RA相关基因或信号通路的调控而引起的。所有先前被描述为与RA病理相关的基因。总而言之,我们的研究结果表明,围产期接触BBP可能会增加后代对RA的易感性,这可能是通过邻苯二甲酸酯诱导的RA相关基因或信号通路的调控而引起的。
